To all whom it may concern:

Be it known that 1, JAMES W. Moons, citizen of the United States,residin at Norfolk, in the county of Norfolk and tate of Virginia, haveinvented certain new and useful Improvements in Detachable Soles; and Ido hereby declare the following to be a full, clear, and exactdescription of the in vention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to new and useful improvements in shoe soleprotectors, the main object of the present invention being the provisionof a protector adapted to be detachably applied to the sole of anordinary shoe to protect the same from heated surfaces and also toprotect the same from unusual wear or uneven and rough surfaces.

A. further object of the invention is the provision of a detachable soleor protector for shoes adapted to be removably applied to the shoe andso constructed as to provide for thorough circulation of air between theprotector and the sole of the shoe so as to prevent the heat from comingin contact with the sole of an ordinary shoe when the person wearing theshoe is obliged to either stand or travel on a heated surface.

A still further object of the invention is the provision of a detachableshoe sole protector which can be quickly and readily applied to anordinary shoe or detachedtherefrom and is preferably constructed oftireproof material to adapt the same for accommodation on heatedsurfaces and also provided with means to insure a circulation of airbetween the sole of the shoe and the protector to prevent the heat fromthe heatproved shoe sole protector, illustrating a shoe in position indotted lines,

Fig. 3 is a transverse sectional view taken on the line 33 of F 2,looking in the direction of the arrows,

Fig. 4 is a longitudinal, sectional View taken on the line L- d of Fig.2, looking in the direction of the arrows.

In the construction of my improved shoe sole protector, the sole portion1 is preferably formed of fire-proof material such as asbestos or thelike, while the heel plate 2 and instep portion 3 are formed of anysuitable metallic material and attached to the inner end of the sole 1by means of the rivets 4, the attachment being preferably made at thepoint where the sole of the shoe recedes into the instep. The soleportion 1 is formed in two separate pieces, suitably stitched togetheras shown at 5, and it will be understood that while I have shown anddescribed the two sole portions secured together by stitching, it willbe understood that any other suitable form of fastening means may beused. The idea of having the sole portion 1 formed in two portions isthat when the outer sole portion, generally indicated by the numeral ibecomes worn down, it can be readily replaced by a new one which willprolong the life of the protector.

In order to space the sole portion 1 of the protector from the sole 6 ofthe shoe as indicated in dotted lines to provide a circulating surfacebetween the two soles, coil springs are disposed between the two solesand in applying the coil springs, which are secured to the inner sectionof the sole, they are arranged to form a plurality of substantiallyU-shaped loops, the ends of which are secured to the inner end of thesole 1 by means of the rivets 7. In attaching the coil springs to theinner section of the sole 1, one end ofthe outer loop is first attachedto the outermost rivet 7 on one side of the sole, thence extendedoutwardly toward the toe of the sole and conforming to the outline ofthe sole, thence extended rearwardly along the other side of the sole tothe outermost rivet on the opposite side of the sole from the firstrivet. The second set of springs is arranged in a similar manner and soon until a sufficient number of series have been arranged upon the soleof the shoe to entirely cover the same. These springs which aregenerally indicated by the numeral 8 are secured to the inner section ofthe sole 1 by stitching as shown at 9, this stitching only extendingthrough the inner or first section of the sole so as not to be exposedto the wearing surface.

In order to secure the toe portion of the sole to a shoe, suitablestraps are provided which include a central strap 10, one end of whichis secured to the toe portion of the sole and extended upwardly andinwardly to conform to the shape of the shoe and having its inner endconnected with one end of the transverse strap 11. This transverse strap11 is formed in two pieces, each piece being secured'to one side of thesole andextended upwardly over the toe of the shoe and the outer endsconnected by a buckle 12. Additional strap members 13 are provided, eachhaving one end secured to the sole 1 and the other end extended upwardlyto conform to the shape of the toe of the shoe and pivotally connectedto the strap 10 at 14:. These straps 13 are preferably disposed at anangle with respect to the strap 10 so as to firmly engage with the sidesof the toe.

of the shoe to securely hold the sole member 1 in position with respectto the sole 6 of the shoe. The heel plate 2 is connected to the sole 1through the medium of the instep portion 3 and the heel plate itself isshaped to conform to the general outline of shoe heels andthe instepplate 3 made to conform with the general-outline of the instep of anordinary shoe having its forward end connected to the sole 1, as shown,by the rivets 4L. The heel plate 2 and the instep portion 3 areintegrally connected by means of the upright portion 15 which is adaptedto correspond with the front face of the heel of the shoe. In order tosecure the heel of the protector to the heel of the shoe, suitableperforated ears 16 are connected with the heel portion at a pointadjacent the rear end thereof and to which the lower ends of the straps17 are fastened, these straps extending upwardly upon opposite sides ofthe shoe and connected by means of the buckle 18. In order to constructa heel of sufiicient thickness to compensate for the thickness of thesole 1 and the spring members 8, there are attached to the outer face ofthe heel plate 2, suitable lifts herein shown as three in number andgenerally indicated by the numeral 19 and are to be formed of anysuitable fire-proof material to correspond with the material in the sole1.

In order to accommodate the heel plate 2 to different sized heels, anadjustable plate 20 is attached to the instep 8 and provided foradjustment by having the plate 20 provided. with the slots 21 in whichare fitted the screw bolts 22, carried by the instep so that the plate20 can be adjusted longitudinally of the protector. The end of the plateadjacent the heel plate 2 is provided with a down-turned flange 23,adapted to be arranged parallel with the portion 15 and adjustable withrespect to the heel plate 2 so that when a shoe heel is positioned uponthe plate 2, the plate 20 can be adjusted so that the portion 23 willengage with the inner face of the heel of the shoe as illustrated inFig. 1. From this, it will be apparent that the heel portion of theprotector can be readily adapted to fit shoe heels of various sizes.

From the above description, taken in connection with the accompanyingdrawings, it will be readily apparent that I have provided a detachableprotector adapted to be used for application to a shoe where it isnecessary for aperson wearing the shoe to stand or travel on a heatedsurface, so as to prevent the heat from reaching the foot of the wearer.This is readily carried out by having the coil springs 8 disposedbetween the sole 1 of the protector and the sole of the 7 shoe so as toprovide a thorough circulation of air between the sole of the shoe andthe sole 1. It will also be apparent that my improved protector can bequickly and readily attached to a shoe or removed therefrom and the heelportion readily adjusted to accommodate various sized heels. It willalso be apparent that in the construction of the sole portion of theshoe, it is preferred to have the same in two pieces or sections asindicated by the numerals l and 2 so that the outer section can bereadily exchanged for a new one when the same becomes worn and that thelift sections 19 on the heel can also be readily interchanged as theinner- I most lift is riveted to the plate 2 by means of the rivets 2 1,while the other lifts are secured to this inner lift in any suitablemanner to permit them to be detached and replaced by new ones should thecase desire.

What I claim is: I i

1. A shoe sole protector comprising a sole portion, a metallic heelportion, connected with the sole portion, a plurality of helical springsarranged upon the upper face of the sole portion to provide an airventilating space between the sole portion of the protector and the soleof the shoe and means for attaching the'protector to a shoe.
